I’m having a hard time finding one. My system will have 11Kw of micro inverter panels, 5kw of standard panels, EG4 or similar battery and a 22kw Generic. I’m “on grid” and would power arbitrage if possible. Ok someone talk me out of this?!?

got my 18K after Signature Solar did their rebate for folks who had bought the 6500ex's. Set it up and it worked like a charm for a couple months. Then all of a sudden my power shut off and it said there was a battery fault. Apparently there had been 'battery voltage high' alarms for a month or so, but the EG4 Monitor app doesn't actually alert you of any of these, it just catalogs them so if you don't look you won't know. Checked all the voltages at the battery terminals as well as at the unit and all were nominal (batteries measured 52 or 53, inverter measured 55V). Signature Solar tech support verified this on their end and said everything was fine. Powered everything on again and even though it is functioning normally it is still sending these alarm codes. SS said it was likely a software issue. Fat lot of good THAT does me. System is set up and working as it should but the software will shut my system down?

@@SunInLithium , Both operate using a sort of pulsing power supply, so the current starts and stops at a super high rate. Light dimmers do the same thing, but the current is low. A mig welder is a double whammy, because it has two pulsing parts: 1) The switching power and variable pulse width control for the electrical arc current; and 2) The "pulse width modulator" that controls the rate of wire feed.

Signature Solar just dropped a load test video yesterday that IMO shows it did better than advertised and cleared up some questions I had there. I am going to buy either the Sol Ark or this one in the next few days. The one question I don't see answered anywhere is whether you can hook up a gas generator to charge batteries with the EG4 and as I want to be off grid and have the ability to do that in winter when it is dark and rainy for days as happens in Texas, having this option is huge for us. We are outside of city and on electric co op so have zero interest in sell back, it doesn't pay. The tax write off and my location does make paying off whole house doable in under 10 years. Would LOVE to know the answer to this one questions. BTW, I get Signature has at times had longer wait times but its the growing pains of growing a business, I am ok with it. I have been very happy working with them. Being understanding and supporting these types of businesses is what leads to better options for this community.

UPDATE. After calling Signature Solar I found the literature that is sent with pretty much all their product from eg4 are all out of date inaccurate. Go ahead and throw all directions away that come with the product and go online to their online instructions/set up. After reading through the online literature it all worked.

[@rowlandcrew]

Hi Will, there are a few details about your test setup that are important to the evaluation of a hybrid inverter. You did good on the performance of the SW interface. there are alot of installations that will want to connect in existing AC coupling, be able to sell to the grid and AC couple when the grid is down. This requires a transfer switch in the EG4 inverter that can manage the isolation. It is not clear how you are testing this mode. Related is the configuration is that many solar systems would be most economically modified by just adding in the EG4 inverter which most generally may also require not having the EG4 inverter near the service entrance. This requires the EG4 be able to control a remote contactor at the meter. It sounds like your shop and house loads are distributed suggesting a this test setup. How does the EG4 do in managing the grid tie when the meter is remote? thank you

Love your videos. Can you do a video on retrofitting a 18KPV onto an existing grid tie system (7.4kw enphase microinverters IQ7+). I ask this because CA is about to push out new electricity rates based on income which will essentially make my net metering benefits obsolete. This rate change makes me want to disconnect from the grid completely. Im curious of the best way to do this with my existing grid-tied micro inverters. I'm thinking of adding the 18kPV and about 30-60 KW of server rack batteries. Does the 18kPV allow one to set up a micro-grid and allow the enphase microinverters to continue to work without a formal grid? Of course I would use a 9KW inverter generator as back up to charge batteries if they ever go below 15% SOC. We do have some cloudy/rainy days here in LA. What do you think? Interested in making the video? I am familiar with off grid systems. Built a 120V, 7 KW solar, 15 KW storage for a cabin we have in Big Sur. Works great up there but really want to build something here that is AC linked with my existing solar. Phase 2 would be add V2H tech when I eventually buy an EV.

Hey Will .. It's great that these systems are getting larger and larger with abilities to support entire homes off grid.

I know for a while, MPP solar had the PIP-1012LV, but I have not really heard anyone else be in that end of the market.

Zero export in hybrid mode is non-functional right now if you can't export anything back to the grid due to no backfeed agreement. Plenty of posts about it on the forum. They have a firmware update that disconnects from the grid using the relay when you have enough charge, but it's not exactly a hybrid inverter at that point. Fast zero export doesn't seem to do anything differently. It's a great unit, but don't buy it yet if you need zero export.

[@therusty959]

@@WillProwse Just give it a quick check, you don't even need secondary test equipment to see if it yours acts like mine. Just uncheck "grid export" and let it run for a bit. It is generally centered at zero, but sometimes exports up to 100 watts steady state, not even in response to a load turning off. The 18k display shows it too. I'd have spikes into the hundreds of watts even at steady state. Definitely turning off big loads it takes several seconds to react - and I think that's perfectly acceptable. That's just the nature of how power has to be reactionary. That's what "Fast Zero Export" should fix by reacting faster at the expense of importing more over time because it must react weighted on the import. However when that gets checked nothing changes. Give it a try, no need to change your hardware configuration.

@@therusty959even signature solar has admitted this to me also (on phone call)

[@VinceBadovinatz88]

Great video😊 I was thinking the same thing about once you go 18 you won't go back haha. What's the minimum PV voltage to make it charge on the 18K...

[@WillProwse]

Thanks! And yeah hard to go back haha! And 100VDC but they recommend 230VDC for maximum performance and efficiency

@@WillProwse thank you

Video with the 18k ac couple with the grid tie solar. Would be a great video on the set up with the 18k inverter. would be great when power goes out and still use the grid tie to supply power to the 18k to power the batteries and power the house. Looking forward to the video.

agreed

BRILLIANT

I wish it would send notifications of alarms via email or had a decent mobile app that could push notifications.

Awesome video very informative thank you!

[@DiySolarHelpDesk]

I partnered with signature solar just so I can offer these to my customers. It's the best Hybrid available.

[@WillProwse]

Right! So nice

[@electricandlspower]

I'm sure they are boring to u and maybe some of us but I enjoy seeing them systems work. Not sure if the videos make any money. Just my 2cents maybe a short would be cool

[@bigblockcutlass123]

My newer eg4 racking is a lot nicer than the one you have, Welded with door. Good Quality. Been running Sol-ark 15 K. Al-some unit but pricing. But for how much the 18k cost and Signatures solar worthless customer service I would spend the extra money.

[@davidchristensen1219]

Can you test the 18K with imbalanced loads? That will be key to put it up against Schneider (XW Pro.) There have been others that tested the Sol-Ark in this manner and it failed vs the Schneider.

[@jtmg11]

This is the essential decision point for myself, how does robustness compare to Schneider

[@CessnaPilot99]

Can you do a video on communication between batteries and inverters? What are the protocols and what is the benefit? You keep mentioning it but I don't understand why it's necessary

[@ninja5672]

Would it be better to run 4x of the 3k units instead of the 18k (actually 12k) unit? 4x3k would be half the price and yes, they could fail, but if one fails, you still have 9kw output instead of zero. Maybe buy 5 and have a spare?

[@wadebrewer7212]

I am curious how it would stack up against the Sol Ark 15k. 🤔

[@drcannabis420]

Setup a big Victron system already. 2 x 10,000 watt Quatro's

[@franklong6269]

Will, what about the Sol-Ark 15K. It has superior user interface, more capacity and can be programmed to customize it in more ways. The interior components of the Sol-Ark 15K are also higher quality. The costs also are about the same.

[@ElderlyIron]

Having watched all three 18K videos, and having a Sol-Ark 12K for 2.5 years, I have a comment and a couple questions. My reason for watching is that I was ready to upgrade to the 15K from the 12K. First, in video #1, you mention the price difference. The Price you posted for the Sol-Ark is the EMP protected price, whereas the unprotected 15K is indeed $2000 less. You also don't mention whether or not the EG4 is EMP hardened. Second, Sol-Ark has a feature to connect a genset in place of the grid, and also the "Smart Load" feature that allows the Generator input connection to be used as an A/C load connection. This particular feature is important to me, as my unit is located remotely from the house, and I utilize the Smart Load feature to power the building that houses the unit. While I AM still grid connected, I have a manual transfer at the house at the fuse box. (Yes, a FUSE box! Built in 1962!) Unless I run a new pole and meter box, I don't have the capacity to connect the grid to the Sol-Ark, which was one of the reasons went with them. And no, it wasn't worth $2K for me to go EMP hardened! P.S. I might have a "gently used" 12K for sale soon! LOL!

[@ElderlyIron]

As an addendum, I find that the max charge voltage for the EG4 is 60v. In a 48v flooded lead acid configuration, temperature compensating needs 61v at a bare minimum with 61.6v being about the norm for any temp at or below 60 degrees F. The Sol-Ark 12K that I run won't go to 62v, but the 15K will, For equalization, Rolls (I use L16 445 Ah x 3 banks) recommends 63 volts, which the Sol-Ark 15K will do, but the EG4 won't. Otherwise, it appears that both of these are fabulous whole house units!

[@pds4184]

Your welcome!

[@mfgxl]

What about reviewing some Outback inverters?

[@phongmai3306]

Very nice system. Can you do step by step installation and wifi setting for this 18k

[@Mike-01234]

The larger 12KW probably runs cooler with smaller systems wonder if it better to go the larger inverter even if you only plan on 6000-8000 watts. If you mount these inside have to cool them running near max capacity generating lot of heat have to cool.

[@diyEVguy]

Very interesting thanks!

[@tenminutetokyo2643]

What a beast!

[@cheetahb5]

Will, been doing a lot of research on these. Still can’t figure out (can’t find it in the manual) how to set the system to charge the batteries from grid when the batteries reach a set SOC. You can trigger a gen at a given SOC and you can set times to charge from the grid, but I don’t see how to trigger a grid charge based on battery SOC.

[@notmarcus421]

Heavily looking at this for my house

[@AlexSwan]

All amazing, unless you live in Australia because we can’t get any of these products.

[@glenmoss8189]

Hi Will. I have one of these inverters and couldn’t be any happier with it so far! Let me ask though for those of us operating off grid or with a zero export constraint, how can we configure the system to turn on additional loads to avoid missing out on solar productivity once the batteries are fully charged? You know loads like bitcoin mining or water heating come to mind.

[@CCRep123]

Will, I have 2 EG4 6500EX's & SS recently offered me a trade in program for them to goto the 18K. I'm trying to figure out why & what the upside is to going to it? I'm completely off grid & likely always will be. Thx for all you do.

[@corba197]

Be careful. Your two 6500s have more output capacity than one 18kpv, because the 18k = input, not output. Of course there are other considerations, but that output comparison is widely misunderstood due to SS's label.

[@CCRep123]

@corba197 agreed. 2-6500's = 13kw. The 18kPV has 12k. I was looking at eventually adding atleast a 3rd 6500 for my +21kw of panels. Being off grid I like the thoughts of redundancy 9f the 2-3 6500's. Some of that is lost with a single 18kPV. But then again, I'm wondering if they may be completely going away from & not supporting the 6500's sooner than later. That said, I really like the simplicity & options with the 18kPV... especially with their new PowerPro/ LUX batteries that are made for each other. If I do the upgrade, the odds are I will eventually end up with 2 18kPV 's for 24kw potential. AND then keep the 6,500's for a backup or AirBnB cabin use.

[@kb7tse]

I had to return my 18K for a DC shorted input. They replaced it.
